This is the X150 mini FPV racing quadcopter from ViFly - one of the worlds fastest sub-250g racing drones! The X150 adopts the X-style frame that is extremely lightweight but still durable. As the name may suggest, this is a 150mm size quadcopter but don't let the size fool you - this quad produces an extremely high performance. Best of all, this is sub 250g so any regulations passed for drone 250g and above will not apply to the X150.
